Kansas Gov. Sam Brownback’s “real live experiment” in supply-side economics has failed—and now the poorest in the state are going to have to pay the costs.

In the end, many Kansans will pay more in taxes due to an increase in sales and cigarette taxes, a freeze in income tax rates and limits for itemized deductions.

It’s well known that these tax increases were precipitated by irresponsible, top-heavy tax cuts championed by Gov. Brownback and passed in 2012 and 2013. An ITEP analysis of all Kansas tax changes over the last four years (including this year’s) found that the poorest 20 percent of Kansans, those with an average income of just $13,000, will pay an average of $197 more in taxes in 2015 as a result of the Gov. Brownback tax changes, and, even with the increases Gov. Brownback is expected to sign into law today, the richest 1 percent are still paying about $24,000 less.
